text: There are two main strands of the modern approach. 
  One is based on the idea that many of the experiments associated with general chemistry (acids and bases, oxidation and reduction, electrochemistry, etc.) can be carried out in equipment much simpler (injection bottles, dropper bottles, syringes, wellplates, plastic pipettes) and therefore cheaper than the traditional glassware in a laboratory, thus enabling the expansion of the laboratory experiences of students in large classes and to introduce laboratory work into institutions too poorly equipped for standard-type work. Pioneering development in this area was carried out by  Egerton C. Grey (1928), Mahmoud K. El-Marsafy (1989) in Egypt, Stephen Thompson in the US and others. A further application of these ideas was the devising by Bradley of the Radmaste kits in South Africa, designed to make effective chemical experiments possible in developing countries in schools that lack the technical services (electricity, running water) taken for granted in many places.
  The other strand is the introduction of this approach into synthetic work, mainly in organic chemistry. Here the crucial breakthrough was achieved by Mayo, Pike and Butcher and by Williamson who demonstrated that inexperienced students were able to carry out organic syntheses on a few tens of milligrams, a skill previously thought to require years of training and experience. These approaches were accompanied by the introduction of some specialised equipment, which was subsequently simplified by Breuer without great loss of versatility.
  There is a great deal of published material available to help in the introduction of such a scheme, providing advice on choice of equipment, techniques and preparative experiments and the flow of such material is continuing through a column in the Journal of Chemical Education called The Microscale Laboratory that has been running for many years.
  Scaling down experiments, when combined with modern projection technology, opened up the possibility of carrying out lecture demonstrations of the most hazardous kind in total safety.
  The approach has been adopted worldwide. It has become a major presence on the educational scene in the US, it is used to a lesser extent in the UK and it is used in many countries in institutions with staff who are enthusiastic about it. For example, in India, small scale chemistry/ microscale chemistry is now implemented in a few universities and colleges.
